How to get shade quickly... and stay away from oaks
Q: I just moved from Tennessee into a new house in Florida and there are no trees on the property, the yard is brutal hot. What can I plant so I have some shade real quick? I like Florida shady oaks, how long will they take to grow?
A: First
of all, do not rush into oak solution. Oaks are beautiful shade trees, however
they have at least 2 problems:
a) Oaks are slow growers and unless you are willing to wait some 20
years... you won't get that desirable shade that quickly.
b) We have hurricanes in Florida... sometimes. A hurricane can damage
any tree, however with oaks it may be the worse case scenario - the branches
of those giant trees are huge, hard and heavy and in unfortunate situation
when you need to remove or trim a broken tree, it may cost you... a few thousand
dollars.
These are solutions that are more economical and practical:
1) Selection. If you have room, get one of these most popular Florida shade trees: Royal Poinciana, Golden Shower, Hong Kong Orchid Tree, Red Kapok, Bottlebrush, and many others. See full list of fast growing shade trees. Or simply get a Mango Tree and have delicious fruit too! Many varieties of Mangos are very large and fast growing.
2) Do it right. Even if you are planting a smaller tree, 1-3 gal
size, it may become a nice shade tree within 2-3 years and start providing
your driveway with desirable shade. The keys for fast growth are -
a) Good soil. Dig as big hole as possible and fill it with good
rich soil containing compost. See planting instructions PDF.
b) Water. Do not rely on sprinklers and rains. Water your tree
daily for the first week, then at least twice a week for another month. After
that, irrigation system will be enough.
c) Fertilizer. Put a few handfuls of fertilizer in a planting hole. Then fertilize once a month during warm
season. Apply micro elements for even better results and faster growth.
3) Ask experts. Contact our office for advice. We will suggest the most suitable shade tree for your yard based on features of your property: location, soil, exposure, etc.

Full Sun Garden vs Shade Garden
"Someone is sitting in the shade today because someone planted a tree a long time ago." (Warren Buffett)
Q: I live in California and I have a large area of my garden in full shade. Are there any plants that will be happy there? I am looking for something colorful. I also have a smaller area in front of the house that has full sun almost all day long, but I am afraid this can be too hot for flowering plants? Can you recommend something?
A:
Full sun gardens have a strong, bright look while shade
gardens have cooler, subdued appearance. Both types of
gardens are fun to design and maintain as long as you pick
the right plants.
Full Sun Garden is the easiest to grow. Depending
on exposure, it may require some plants that can tolerate
the hottest summer days and the dry conditions in your
area. The good news is, the majority of tropical and
subtropical plants prefer full sun, so you have a large
selection to pick from - fruit trees, flowering trees,
shrubs, vines, and small perennials. The more sun, the
more flowers and fruit you will get! However, keep in mind
that sun gardens require more water, but generous mulching
will help to minimize watering.
Shade Garden is much more restful in appearance,
but sometimes may be a little more difficult to work with.
As shade trees grow bigger and thicker, it may become too
dark; nothing will grow in total darkness. In this case
you need to prune back some branches to let more light in.
Filtered sunlight or dappled light coming through the
leaves of the trees is beneficial and considered light
shade, which would be the best light conditions for shade
loving plants to thrive. Although shady cooler spaces
attract more insects and will require more attention to
control them, they also have some advantages over sun
gardens. You can enjoy working in cooler conditions, and
your garden will require less water. Many foliage plants
look more deeply colored and healthier than in full sun;
white flowers shine instead of looking washed out!
Our favorite shade plants are fragrant brunfelsias , clerodendrums, and of course
colorful gingers and heliconias. You
may also consider ornamental foliage of Calatheas, lush Alocasias, Colocasias, and colorful Cordylines. Check out our shade loving plant list for
more colorful suggestions. These are also great for indoor
gardens!

Quick shade for your driveway
Q: Please help! We just moved into a new house in Florida and don't have any mature trees yet, but the sun is already brutal! Can you suggest any super-fast growing shade tree that can make shade over my driveway as soon as possible?
A: Check out Giant Potato Tree - it is very fast growing, has very large leaves plus very pretty purple flowers as a bonus year round! The pictured tree was planted from 3 gal only 6 months ago, and already covers with shade the whole car. It is small to a medium size tree, but one of the fastest growing. If you are looking for a larger tree and willing to be more patient, here is the full list of tropical and subtropical fast growing shade trees. Most of them may take a few years until they reach a mature size, however, in order to enjoy your shade tomorrow, you must plant the tree today!

Horned Holly - a cool bonsai plant
By Onika Amell, tropical plant specialist
Q: I live in Chickasaw, Alabama. I am a beginner bonsai grower. I received a lovely little Horned Holly as a birthday present and I want to know if it is a suitable plant to bonsai?
A: The Ilex cornuta - Horned Holly, or Chinese Holly, is very popular as
a bonsai species. It is loved for its very beautiful and distinctive
rectangular foliage and for its small, white flowers which give way to large, red
berries. The berries are larger than those of the European Holly. The leaves are
rectangular and unusually shaped with three large spines at the apex. This
bonsai will take both sun and shade, but semi-shade is preferred in midsummer.
If indoors, give it plenty of bright light. When kept outdoors, your Horned
Holly bonsai will need some frost protection and should be sheltered from
strong or cold winds.
It will need a fair amount of water and should not be allowed to completely
dry out. Watering during the heat of summer is especially important, as well
as in spring right before the fruit production, and should be reduced during
winter. This species will also appreciate regular misting of the foliage.
Repot this bonsai every 1 to 2 years in early spring, using bonsai soil - TopTropicals
Adenium Soilless Mix. Fertilize the holly every two weeks throughout the
growing season using either a balanced fertilizer diluted to half strength.
We recommend for this purpose Tropical Greenhouse Plus - Plant Booster. Pruning should be done in
early spring.
Horned Holly is also very popular as a hedge plant as it grows dense
and compact. It will grow to between 3 and 5 feet tall and will spread to an
equal distance, giving it a round, shrubby form. It is cold hardy! Zones 6
through 9. It will tolerate a wide variety of soils as long as it is
well-drained. It likes sun or part shade. It is heat and drought tolerant once
established, and are often used in xeriscaping. Its branches produce dark olive-green
foliage that is often cut for indoor decorations during the holidays.

Seeds germination in summer
Q: What is the best way to germinate seeds in summer? Should I keep trays indoors or put them outside?
A: Summer is the best growing season for plants, and for their propagation. Seed germination process of tropical plants usually benefits from warm, and even hot temperatures, so keeping pots with seeds outside in full or partial sun can be the best way. However some seeds may be more sensitive than others, or require slightly cooler or higher temperature for germination. These are a few tips that may help:
- For seed germination, use only well drained mixes, containing either peat moss or coconut fiber to retain moisture. Some succulents may require adding sand to the germination mix. You may also try our Professional Formula Seed Germination Mix.
- Large tropical seeds, like palms, or seeds of Fabaceae (Bean) family, can be grown in full sun. Their germination will benefit from higher temperatures (up to 90-95F). Make sure to keep soil moist. Cover them well, with 3/4 to 1 inch of soil.
- Fruit seeds (large size) should be germinated either in individual cells or small pots (3-4" diameter).
- Small to medium size seeds can be grown in so-called community pots. Seedlings can be separated after they establish their first roots.
- Tiny seeds should be planted closer to the surface, covered with only 1/4-1/8 inch of soil; some seeds require bright light for germination, so full sun will be a plus. Some small seeds like Ficus for example, prefer to be broadcasted on the surface, uncovered. Put containers with such seeds in bright shade, as you don't want the surface of the soil to dry out.
- Once your seeds sprouted, move them in filtered light - bright to medium shade depending on tenderness of the species. (Gingers prefer shade, while succulent sprouts can stay in brighter light). Regardless of water/sun needs of the species, all young sprouts and first leaves are sensitive to hot sun and may get burned or even killed. Once a baby plant has a few leaves and well-branched root system, you may start moving trays into a brighter light.
- Do not overwater young seedlings, keep soil slightly moist but not soggy.

Care of Desert Roses
Q: I am looking forward to my three desert roses I just ordered from you and I am wondering how to take care of them, especially during winter time. Should I put the pots in full sun or shade? What kind of soil do they like? How often should I water them? When it gets cooler, should I bring them inside? We do have occasional frost here during winter.
A: Here are a few tips for your desert roses:
1. When received Adenium from mail-order, unpack carefully; branches are fragile. Plant in well-drained potting mix. Cactus mix will do, but we recommend special Adenium mix. If using regular acidic peat-based potting mix, you may add sea-shells on top of soil to neutralize acidity: adeniums prefer alkaline soils. Using clay pots is beneficial. Water once and do not water again until soil gets dry. Place in bright shade until new leaves sprout, then the plant can be moved to full sun.
2. Adenium is a succulent, but not a cactus. It needs watering, however let soil dry before waterings. Reduce watering during cool season and discontinue when plant gets dormant (drops all leaves in winter).
3. Bright light is the best for profuse flowering. However, adeniums look much healthier in slightly filtered light rather than in all-day full sun.
4. Fertilize and spray leaves with liquid fertilizer SUNSHINE Megaflor - Nutrition Bloom Booster. Phosphorous is responsible both for flowering and caudex development. Avoid caudex, spray over foliage only. Dry fertilizer can be used only during hot months.
5. Watch for spider mites during hot and dry season.
6. Give plants a break during winter dormant season. Keep in bright shade and reduce watering to 1-2 per month or stop watering if temperature is below 65F.

Q: I live in California and about a month ago ordered several plants from you, including fruit trees (Carambola, Mango, Avocado) and flowering trees (Xanthostemon, Adeniums, Champaca, Ylang Ylang). They were all doing well until I tried to move them into full sun, when they got leaf burn immediately. Ylang Ylang was doing great in a shade, but I repotted it from 1 gal into 3 gal and it is drooping leaves now. It has been very hot (over 100F) and dry (humidity is less than 25%). Any suggestions?
A: Hot summer can be pretty challenging time for establishing new plants. These are some guidelines to make your summer gardening more successful and rewarding.
1. You can order plants at any time, but keep your eye on your local weather forecast and try to chose cooler periods to schedule your plant shipments. Here at TopTropcals we monitor weather at destinations, and we can also delay shipment per your request until more favorable conditions.
2. During hot Summer months, many plants are still OK to ship, and to be planted, many species are heat tolerant. It's usually safe to ship most succulents, including Desert roses and Euphorbias. Some fruit trees are pretty easy too, like Loquats, Mango, Eugenias. Many flowering trees can take heat: Acacias, Clusias, Jatropha, Sausage Tree, Plumerias and many others. Check our full list of plants suitable for hot and dry conditions. Most jasmines, including Jasmine Sambac and Trachelospermum make also a safe choice for hot weather planting.
3. Use shade cloth or simply white sheets to protect young plants and new plantings from hot sun.
4. When establishing mail ordered plants during hot weather, keep them in shade for longer period of time than average recommended 1-2 weeks. Give them a chance to establish really well. In areas with low air humidity, try to create a simple mist system. It can be purchased in your local Home Depot for only $20 and set up takes only 10 minutes! It makes a big difference and can help you save many plants from hot weather stress.
5. Although it may seem that during hot weather plants need more water due to high evaporation, be careful with watering, and check soil with your finger before watering - don't water if it is still wet. Combination of "hot and wet" can be as harmful for the root system as "cold and wet" during winter. Protect root systems from overheating: covering black pots with white cloth will work. Remember when temperature is above 90F, most of plants slow down their metabolism, which means roots slow down or even stop pumping water and become more vulnerable to overwatering. For the same reason, do not hurry to step up into bigger container if roots haven't filled yet the existing pot.

Colorful Yesterday-Today-Tomorrow
Q: I have a large oak in front of the house and nothing grows under it, even grass. Can you recommend me a compact, colorful flowering shrub that will tolerate shade location and still will bloom for me? I love fragrant flowers, that would be nice... Also, I am a snowbird staying in Florida mostly from Fall to Spring so I miss the flowering season! Any winter bloomers? Or am I asking for too much?
A: There is a plant for every location and every need! Here is a
perfect plant for you, Brunfelsia grandiflora - Yesterday-Today-Tomorrow. It is a winter
bloomer and it enjoys filtered light. In fact, in full sun Brunfellsia leaves
sometimes turn yellowish, so a shade location will be perfect for it, leaves will
be healthy and dark green.
It is a beautiful specimen plant. The unusual popular name of this
medium-sized shrub becomes clear to anyone who observes it over the course of two
or three days. Its tubular fragrant flowers change from purple to lavender
and then to white over a three day period (First they open as rich
lavender-blue; then they change to pale lavender and finally to almost white before they
fall). Then all three colors can be seen on the same plant. It grows to
about 3-6 ft and does best in filtered sunlight. Blooms fall to winter.
Check out all Brunfelsias from our store - they all are shade lover and free-flowering!

Monster hybrids of Monstera: juvenile and mature
by Mark Hooten, the Garden Doc
Q: I am a rare plant collector and obtained a very interesing cultivar of Monstera from you that says it's a hybrid Monstera adansonii x obliqua. Is there a named hybrid? The leaves on this specimen that came in 1 gal pot are much larger than the plant I have grown in a 3 gal pot for a few years, under name of Monstera friedrichsthalii.
A: Due to their diversity, it is hard to find verified hybrids in the genus Monstera. M. friedrichsthalii is apparently an old Florida name for what is actually technically M. adansonii. The "primitive" juvenile growth is very different from the much larger more robust form that only occurs when it is allowed time to climb a tree, in which case the foliage becomes very different and much larger with many many more fenestrations (holes) of various sizes. If you visit our Garden Center, you can see the mature form climbing the oak tree in our Shade Garden in front of our office - we use this mature plant for propagation. If you take a cutting and don't let it attach to a bark/trunk and climb upwards, it will quickly revert to the wimpy juvenile form. Seems that even climbing a pole indoors, it never actually develops into the truly mature more complex adult stage. Some juvenile forms growing on a tree if given too much shade, do not develop into the larger mature form. Move it in more light and allow it to climb, and it will look very different, but still is the same plant under different conditions.

Pretty in Pink... and Purple Prince for her!
By Onika Amell, tropical plant specialist
Q: I have a bare spot in my front garden, behind a low wall, in part-sun. I'm hoping to find an evergreen, flowering ground cover that will cover it quickly. Any ideas on finding something with the ability to eventually also cascade over that wall? I live on Marco Island, Florida.
A: Barleria Repens - Small Bush Violet, is a tough, fast-growing evergreen
that blooms from late spring to autumn. Of the many Barleria we see in the
tropics, Pretty in Pink is one of the most striking! The name tells the whole
story: pretty and pink. A lot of gardeners enjoy using them as a ground
cover. They will quickly cover a large area - their stems root readily as the
plant crawls along. They are easily propagated by lifting the rooted runners or
using cuttings. They also reseed easily. Flowers are followed by seed pots
that explode open when dry, dispersing 4 seeds at a time! But perhaps best liked
by many gardeners, is their habit to cascade. It will be well suited for
covering the bare area in your garden and spilling over that wall beautifully.
When used as a ground cover, remember to pinch out young shoots to
encourage bushiness and prune the plant back hard after flowering to keep it
neat.
Barleria repens will also adapt to different situations in a garden if
you need them to. Although they usually form a rounded to spreading bushy
shrub, 2 ft high by 3 ft wide, they will climb when you give them support. They
are often allowed to lean into nearby trees and shrubs.
Hardy to 28F, Barleria repens is pest-free and fairly frost-tolerant.
They love sun and part shade, as well as well-drained soil and plenty of
organic material. Avoid planting it in deep shade as it will get leggy and
reluctant to flower.
They will thrive when fed with a slow release fertilizer at intervals
of 6-8 weeks, throughout the growing season.
There is another cultivar of this exact variety that has blue-purple flowers, it is called Purple Prince! It couples perfectly with Pretty in Pink! :)
